9/50 = 0.18
0.18*100 = 18%
Answer:
80
Step-by-step explanation:
1/3 of 120 is 40
If 40 leave
People left in party=120-40=80
(10/17) / (-15/17) =
10/17 * - 17/15 =
- 10/15 =
- 2/5 <==
============
2.75 / -2.2 =
- 1.25 <==
============
(-2 3/5) / (3/5) =
- 13/5 * 5/3 =
-13/3 or - 4 1/3 <==
============
(2 1/4) / (3/4) =
9/4 * 4/3 =
9/3 =
3 <==
Step-by-step explanation:

Factor by grouping,

Complete the square, with the x variables,

Factor out 25 for the y variables

Complete the square

Simplify the perfect square trinomial

Make the right side be 1 so divide everything by 25.

Here our center is (7,2).
Answer:
5/7
Step-by-step explanation:
We have two points ( 2,-2) and (9,3)
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 3- -2)/( 9-2)
= ( 3+2)/(9-3)
= 5/7
